How to right align PreferencesActivity in android?

Question

I have PreferencesActivity which I need it to be right aligned because I want to use Arabic language, I tried to use android:layout_gravity=\"right\"

Answer 1

for preferences fragment you can make its container to have this attribute

android:layoutDirection="rtl"

Answer 2

create a layout xml file called preference_checkbox.xml paste this (change the colour to what you want, only the gravity and the width set to fill parent are important) :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight"
android:gravity="center_vertical" android:paddingRight="?android:attr/scrollbarSize">

<RelativeLayout android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:layout_marginLeft="15dip"
    android:layout_marginRight="6dip" android:layout_marginTop="6dip"
    android:layout_marginBottom="6dip" android:layout_weight="1">

    <TextView android:id="@+android:id/title"
        android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="right"
        android:singleLine="true" android:textAppearance="?android:attr/textAppearanceMedium"
        android:ellipsize="marquee" android:fadingEdge="horizontal"
        android:textColor=#000000 />

    <TextView android:id="@+android:id/summary"
        android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="right"
        android:layout_below="@android:id/title" android:layout_alignLeft="@android:id/title"
        android:textAppearance="?android:attr/textAppearanceSmall" android:textColor=#000000
        android:maxLines="4" />

</RelativeLayout>

<!-- Preference should place its actual preference widget here. -->
<LinearLayout android:id="@+android:id/widget_frame"
    android:layout_width="wrap_content" android:layout_height="match_parent"
    android:gravity="center_vertical" android:orientation="vertical" />

</LinearLayout>

and then in the preferences xml file for each row in the settings list that you want to right align add this: android:layout="@layout/preference_checkbox"

thats it!
got the solution from : http://stackoverflow.com/questions/7094584/checkboxpreference-with-own-layout
the question there was about check box with image but it's the same technique.
Good Luck.
